Current Guidance on Preparing Dredged

Material Management Plans (DMMPs):

ER1105-2-100

Dated 22 April 2000

Appendix E, pages E-68 to E-83

BUILDING STRONG®

All federally maintained navigation

projects must demonstrate there

is sufficient dredged material

disposal capacity for a

minimum of 20 years.

Corps Policy

• Sound management of dredged material is a PRIORITY mission

• Conduct dredging & manage dredged material in an

environmentally sound manner

• Ensure each navigation project has a dredged material

management plan that assures warranted & environmentally

acceptable maintenance of a navigation project

• Include potential beneficial uses of dredged material

• Achieve dredged material management goals within authority

DMMP Planning and Implementation

BUILDING STRONG® 7

Preliminary Assessment

Existing Projects:

An Initial Assessment should exist

for each existing navigation project.

• Prepared by District Operations

• A “one pager”

• Establish the Management Plan for the project

Must state:

A. Commerical use of channel

B. Sufficient dredged material disposal capacity for a 20

year minimum ? (If “NO”, then a Preliminary

Assessment must be prepared)

PA and DMMP Development

PRELIMINARY ASSESSMENT

Prepared using readily available

maintenance and usage

information. May establish Base

Plan and confirm continued

maintenance appears warranted.

•If YES, completes requirement

for management plan.

•If NO, recommend a DMMP

DMMP STUDY

Establishes Base Plan and if

necessary the recommended Plan

(if major problems, major new

investment or significant increase in

maintenance costs).

Two Phase Process:

Conduct Initial & Final phases:

• Initial phase: Scope of Work

• Final phase: Executes Scope of

Work

Roles and Responsibilities of Planning and

Operations

O&M Projects:

Operations has

program management

responsibility.

Planning conducts

required Studies.

Both offices must

ensure efficient use of

shared resources.

Feasibility Studies:

Planning administers &

conducts Management

Plan Studies.

Operations is essential

participant & assumes

responsibility for

dredged material

management following

project completion.

Funding of PAs and DMMPs

• Preliminary Assessments (PA) funded from available O&M

funds. Limit of $20,000.

• Requests for funding for DMMP for $150,000 or less

included in O&M funding request (PA must be completed)

• Requests for funding for DMMPs costing more than

$150,000 considered on a national priority basis.

BUILDING STRONG® 12

DMMP Formulation

•Consider full range of Alternatives: extending life of

existing sites, combination of new disposal sites with

different methods, disposal area locations & periods of use,

measures to reduce dredging requirements.

•Beneficial uses of dredged material: assess for meeting

both navigation and other purposes including fish & wildlife

creation/restoration, hurricane & storm damage reduction

and recreation.

BUILDING STRONG®

•Beneficial use included in Base Plan is a general navigation

O&M component.

•Uses which are not in Base Plan are separable elements of

the management plan and are pursed under other

authorities.

•However, they should be pursued in conjunction with Base

Plan to assure timely availability of dredged material.

DMMP – Formulation (continued)

BUILDING STRONG® 14

DMMP Budgeting

Existing Projects

• DMMP costs for continued maintenance of federal navigation

projects are O&M costs and federally funded

• Cost sharing partners must pay the costs for their participation

• Budgeting priority limited to Base Plan. Components attributable to

local or state laws are non-Federal costs.

• Activities not required for continued maintenance should be funded

by non-Federal interests

• Modifications requiring Congressional authorization must be

pursued as feasibility studies

BUILDING STRONG® 15

DMMP -Two Stage Process Initial Phase - Scoping:

• Degree of engineering, environmental & economic risk &

uncertainty

• Related activities including surveys outside of project limits,

sources of contamination and non-point sources of pollution

only included if non-federally funded

• Need for project modification requiring Congressional

authorization? If so, pursue new feasibility study through

budget process

BUILDING STRONG®

DMMP-Initial Phase

Initial Scope of Work:

• Basis for total study cost, duration and cost-sharing, if any 36-month

limit.

• Addresses work tasks, milestones, schedule, costs, responsibility, non-

Fed coordination, regulations/guidance.

• Presents minimum level of technical & scientific detail for Final Phase.

• Include tasks (with costs) to support higher level review and approval of

report (i.e. responses to comments, report revisions, meeting

attendance, etc.)

BUILDING STRONG® 17

DMMP – Final Phase

Final Phase provide:

• Complete initial study, results, & findings

• How compliance with applicable statutes, executive orders & policy

is achieved

• A sound & documented basis for decision makers at all levels

• District Commander’s signature, with submittal to Division

Commander for further action

PA and DMMP Report Outline

• Project Description(s) [include project map(s)]

• Scope of Study [indicate whether single project or group of projects;

relationship to permittee dredging, etc.]

• Authorization and Development History [include all project

authorizations, Section 221 agreements, Project Cooperation

Agreements (PCAs), Project Partnership Agreement (PPA),

easements, fee acquisition, construction dates, etc.]

• Description of existing conditions

BUILDING STRONG® 19

PA/DMMP Report Outline (cont.)

• Projections of future conditions in the absence of a Management Plan

• Concise statement of specific problems and opportunities

• Alternative plans:

o Alternative disposal measures to address identified

problems and opportunities

o Beneficial uses alternatives

o Reasons for selecting and combining

measures to form alternative plans

o Evaluation of Alternative Plans

o Trade-off analysis

BUILDING STRONG® 20

DMMP Report Outline (cont.)

• Selection of final plan

o Discuss rationale for selection, sensitivity analysis, and risks and

uncertainties

• Description of selected Management Plan

o Plan components

o Implementation requirements and schedules

o Consistency with the Base Plan

• NEPA documentation, as required

• Results of coordination with local, state and Federal agencies

o Recommendations

BUILDING STRONG® 21

DMMP Approval Process

Division Commanders ensure full technical review of DMMP and

may approve them EXCEPT if:

• Item of work required which qualifies as major maintenance

• Adjustment to District funding targets is required

• Additional Congressional authority required

If one or more of these cases applies, Division Commander

sends Final DMMP & NEPA Document to HQUSACE for

review & approval. Record of Decision (ROD ) to follow.

BUILDING STRONG® 22

New Project Partnership Agreements

DMMPs requiring new capital investments (i.e. new

disposal facility)? need a PPA.

Draft PPA & financing plan

Developed & submitted concurrently with DMMP

DMMP serves as decision document for PPA

PPA requirements should be discussed with sponsor

NO commitments to sponsor until DMMP and draft PPA

are approved.

After DMMP approved, finalize negotiations with sponsor

and submit PPA package to HQUSACE for review.
